解决pycharm问题：module 'pip' has no attribute 'main'

今天在用pycharm下载module的时候忽然就报错： module 'pip' has no attribute 'main'

解决办法是找到Pycharm的安装目录下面的Contents/helpers下面的packaging_tool.py

把do_install 和 do_uninstall两个方法从

def do_install(pkgs):
    try:
        import pip
    except ImportError:
        error_no_pip()
    return pip.main(['install'] + pkgs)


def do_uninstall(pkgs):
    try:
        import pip
    except ImportError:
        error_no_pip()
    return pip.main(['uninstall', '-y'] + pkgs)

 

改为为：

def do_install(pkgs):
    try:
        try:
            from pip._internal import main
        except Exception:
            from pip import main
    except ImportError:
        error_no_pip()
    return main(['install'] + pkgs)


def do_uninstall(pkgs):
    try:
        try:
            from pip._internal import main
        except Exception:
            from pip import main
    except ImportError:
        error_no_pip()
    return main(['uninstall', '-y'] + pkgs)

从新启动Pycharm，搞定！
